So I've seen all the videos and transgender claims. Wouldn't there be a way to prove it? Technically any hair or other DNA sample would prove it one way or the other... Granted, it wouldn't be super easy to get a sample but it's not impossible. Perhaps under the right pretext, a sample could be obtained voluntarily through some political event / gift that would happen to have a sample on/in it. Legally, is there any law against testing someone else's DNA for a Y chromosome? Is that something that someone would get into legal trouble for?
